Time Scale

Fiber Telecom is hosting a local AS112 instance advertised to our upstream and peering connections.
We are one of many volunteer operators participating in the AS112 project, which helps reduce the load on IANA blackhole servers in answering DNS queries for addresses reserved for private use.
For more information visit www.as112.net.

The Replies by Rcode plot shows the breakdown of RCODE values in DNS responses:

  • NOERROR - No error condition.
  • SERVFAIL - The name server was unable to process the query due to a problem with the name server.
  • NXDOMAIN - The domain name referenced in the query does not exist.
  • REFUSED - The server refuses to perform the specified operation for policy reasons.
  • NXRRSET - Some RRset that ought to exist, does not exist (used in dynamic updates).
  • Other - All other response codes, including: FORMERR, NOTIMP, YXDOMAIN, YXRRSET, NOTAUTH, NOTZONE.
